MACHINE FOR ORNAMENTING WIRE.

SPECIFICATION forming part of Letters P .To all whom it may concern:

Be it known that I, JAMES A. CHARNLEY, of the city and county ofProvidence, and State of Rhode Island, have invented a new and usefulImprovement in the Art of and Machine for Ornamenting Wire; and I herebydeclare that the following is a full, clear, and exact description ofthe same, reference being bad to the accompanying drawings, forming partof this specification.

This invention has reference to an improvement in the art of ornamentingwire forjewelers, and in an improvement in the machines by which thenewarticle is produced.

The invention consists in ornamenting wire by rolling with rolls onwhich two patterns are formed spirally around the'rolls, so as to form asuccession of alternating patterns on the wire.

The invention further consists in connecting two or more rolls bydriving mechanism, with their axes diverging from parallel lines, sothat they approach nearer together at one end than at the other, saidrolls being engraved with a spiral pattern or patterns,as will be morefully set forth hereinafter.

Figure 1 is a top view of my improved machine for ornamenting wire. Fig.2 is a vertical sectional view of the same. Fig. 3 is a view of a pieceof ornamental wire in which the lines or ornamentation are placed inalternately-opposite directions Fig. 4 is a view of a piece ofornamented wire made in alternating sections. Fig. 5 is a view of apiece of ornamented wire in which the ornamentation is continuous. Fig.6 is a view of a piece of ornamented wire in which alternatelyornamented and plain globes are formed.

Ornamental wire for jewelers use, has heretofore been made by rollingbetween engraved rolls, but the action of the rolls was not continuous.Skilled labor had to be employed to attend upon the rolls and theadjustment of the same. By my improvement the wire is gradually operatedupon and fed automatieall y by the rolls. The cost of engraving therolls is also much reduced, as only the ends of the rolls require thefinished pattern engraved on the same.

In the drawings,'A A A are three rolls supported in bearings near theirends. The cenposite end. The two outer rolls atent No. 254,197, datedFebruary 28, 1882, Application filed December 27, 1831. (No model.)

tral roll has a fixed bearing, and the axis of this roll is at rightangles to the frame; but the two side rolls have sliding adjustablebearings B B, and their axes are not at right an gles to the frame, norparallel to the axis of the central roll; but the axis of each of theside rolls is farther from the axis of the centralroll at one end thanon the opposite ends of the rolls. The surface of the rolls is therefore closer together at one end than at the opare ad jnsted by theset-screws O O, which turn in screw-threaded bearings made in the endsof the frame,and

are secured to the sliding bearings B B.

D D D are worm-gears secured to the driving ends of the rolls, andmotion is imparted to the rolls by means of the Worm E gearing into theworm-gears D D and driven by the pulley F.

g g are guides, between which the wire is fed and maintained at the biteof the rollsthat is to say, at the point where the rolls are closesttogether.

The wires are fed in at the end where the rolls are farthest apart, andthe distance between the rollsis such as will allow the wire or rod topass freely between the rolls at that end. Therolls gradually approachnearer to each other and' impress the pattern or ornamentation deeperand. deeper on the Wire until the wire is surrounded by asharply-defined design or ornament, when it leaves the rolls. Thepattern is engraved upon the-rolls on a spiral line, in the same manneras a worm or screw-thread is formed. As soon, therefore, as the wirecomes in contact with the rolls it rotates with the same and is drawnthrough the rolls by the spiral direction of the axis of the pattern,and at each rotation the pattern is pressed deeper into the Wire, thewire being held in place by the guides g g and delivered in the finishedcondition.

When a continuous pattern is to be rolled on the wire the rolls areengraved with the pattern placed spirally around therolls; but thedelivery ends of the rolls only require the finished pattern, as thewire will be first operatedupon by the part of the rolls nearly thethickness of the wire apart, and in rollingbetween the rolls isgradually drawn to the finishing end.

" 6, consisting Various forms of alternate patterns-either in form orthe shape of the wire-oan be produced by my improved rolls, in which Iform spiral paths around the cylinder and engrave them with differentpatterns. One form of the wire thus produced is shown in Fig. 4; but theconfiguration of the wire may also be changed in such rolls, and headedor other ornamented wire produced.

h h h are spirals out into the rolls. They are coneaved channels, oneset of which is engraved, and they form the wire shown in Fig. ofalternately ornamented and plain balls. Both balls may be ornamentedwith the same or diiferent patterns, and one ball may be made smallerthan the other by changing the form of the concaved spiral channels h h;or one of the spiral channels h It may be concave and the otherV-shaped, so as to produce alternate balls and cones. It will thus beseen that a great variety of ornament may be rolled on the wire bymyimproved machine.

It will be seen that two wires are operated upon in this machine at thesame time, as one wire is fed on each side of the central roll.

Thus by using three rolls double the amount of work is accomplished thatcould be done by two rolls.

Having thus described myinvention,Iclaim as new and desire to secure byLetters Patent- 1. A machine for ornamenting wire,consisting of two ormore rolls having two continuous spiral grooves formed on the same, oneor both of which is engraved so as to produce ornamented designs, asdescribed.

2. A machine for ornameuting wire, consisting of a central rollsupported in fixed bearings, and two rolls, one on each side of thecentral roll, supported in adjustable hearings, on which rolls a patternis engraved, the axis of which passes spirally around the roll,asdescribed.

3. The combination, with the central roll A and the two side rolls A A,of the adjustable bearings B B, the screws 0 0, and the guides g 9,arranged to roll and ornament two wires simultaneously, as described.
